Manage your symptoms:

  • Rest as needed. Do not plan too many activities for one day. Take short naps when you need them.
  • Eat a variety of healthy foods. Healthy foods will help your body stay strong during treatment. Healthy foods include fruits, vegetables, whole-grain breads, low-fat dairy products, lean meats, fish, nuts, and cooked beans. Eat small meals more often if you have nausea. You may need to meet with a dietitian to help you plan your meals.
    Healthy Foods
  • Go to physical, occupational, or speech therapy as directed. A physical therapist can help you increase movement, strength, and coordination. An occupational therapist can help you find ways to do your daily activities more easily. A speech therapist can help you improve your speech.
  • Get support. A brain tumor can change the way you act, think, and feel. Your memory, concentration, and ability to learn may decline. You may feel anxious or depressed. Talk with family and friends about these changes and about continuing care and treatments. Talk with your healthcare provider about counseling or therapy. This may help you manage anxiety and depression. Join a support group to speak with others that have gone through treatment.

Follow up with your doctor or oncologist as directed:

Write down your questions so you remember to ask them during your visits.
